Appiicauon ined zuiy ai, ieii. serial Nq. 641,505.

Be it known that 1. l\loirrii\ii;n L. Paolina, a citizen of the UnitedStates, residing at Columbus, in the county of Franklin and State ofOhio, have invented certain new and useful Iiniiiovements in Combined(las and Coal Ranges, of which the following is a specification.

My invention 'is an iiiiproi'ement in a combined gas and coal range, andis particularly designed in an endeavor to remedy numerous existingdiliiculties in devices of this type, with particular reference to theutilization of the natural tendencies of prod ucls of combustion intheir course of travel through the range.

The main object of my invention, therefore, resides in the provision ofa structure adaptable for use with either solid or gaseous fuel. Incarrying forth this object. 1

ave provided a damping means operable when in one position to break thecommunication of the gas heating means with the ilue pipe to enable theescape of the products of combustion from the solid jfuel heating meansafter they have passed entirely around the oven. Likewise, when thisdamping means is in the other position, it permits a direct flow of theproducts of combustion from the solid fuel heating means into the flueand also establishes aroinmunicatioii between the flue pipe andtheinterior ot' the oven.

Referring to the accompanying drawings, yin which similar characters ofreference designate corresponding parts: Figure 1 is a front elevationof my combined gas and coal range, Fig. 2. is a vertical longitudinalsection taken through Fig. 1. Fig. 3 is a. section taken in line 3-3 ofFig. 2, looking in the direction of the arrows, Fig. 4 is a lsectiontakenon'line 1 -1 of Fig. 2 and looking in the direction of the arrows,Fig. 5

is a section on line 5-5yof Fig. 2 looking in the'diiection ofthe arrowsand showing the section complete, Fig. G is a vertical transversesectiontaken through my improved type of tire box, Fig. 7 is a sectionltaken on line 74-7 of Fig. S, Fig. is a vdetail plan of an improved.type of oven shelf utilized by me, Fig. 9 is an edge View of suchshelf, Fig. l0 is a detail view in section showing a peculiar structureof passage for the heat fumes, Fig. 11 is a projected section of thedetail shown in Fig. 12, Fig. 12 is a rear elevation of the' castingused in the structure shown in Figs'. 12 and 13, Fig. 13 is an-v lerably carries a. shelf 3., ,which has an addi tional function in thatit assists in supporting the heat dispensing structure. That. part ot myrange which has been designated the heat dispensing unit, is bestillustrated by.`

the structures shown in parts in Figs. 2, C and 7. It comprisesprimarily a fire-box structure 4 having Walls 5 and (i, bed plates 7 androcker bars 8. These walls of the i'ire box may be i'aried inV form, butthe wall C is desirably prmided'iiith a supplemental wall 9 forming achamber 1() which is provided with an inlet pipe 11 and an outlet pipe12. purpose of introducing and withdraw ng .i5 These pipes 11 and 12 are.tor the .-1

water from the chamber 10 with tl'iebbject in View of heating suc-hwater in its passage' through the chamber and such 4passage vislengthened by the provision of a horizontal flange or baille 1373. ltwill be seen that, when the lire box is in use, any water passing.

through the chamber 10, will necessarily he heated. This heating actionmay lbe further enhanced by the lighting of a burner 14 disposedw-ithout the fire box and beneath the chamber 10 and such burner maybeused either independently o'r simultaneously Vvwith the use of thefire box. 1 desii'ably mountan ash receptacle of any type as at 19,which receptacle is supported "within the casing 2O preferably havingsome type of door iii its front face as at 2.1.

The mout-h 'of the fire box is desu-ably in aliiiement with an opening22 in a.- lid. supA adjacent opening 24. Carried by the frame 23 withintheopening .are lugs for carf rying brackets Q-(serving as supports for.the detachable. burn'egs -7'which extend through the wall 'of 'therange just aboi'e the .fire

Below the liie'box,

vporting frame 23 further lprowided with an box 'and are connected tothe gas supply pipe 28 by the short pipes lllupon the burners and bellinout-hs 30. The walls and (3 of the lire box are provided with flangefingers 31 and 32 toi' assisting to support them in vertical and normalposition. The opening 31 of the frame i235 is likewise provided withlugs 33 for carrying brackets 34 serving :is

supplemental supports for the gas burners 35 having short pipes and bellmouths and being substantially similar to the burners 27. The openingsin the wall of the range which partially support the gas burners 27 and35, are adapted to be closed by the pivoted caps 30a shown in Fig. 1 ofthe drawings. The pocket beneath the opening 24 may be designated 36 andis separated from the re box by a. wall 37 which connects at its rearend with a wall 38 forming a 1ongitudinal passage '39 in the rear of thefire box, shown best in Figs. 2, G and 7. Lids may or may not be placedupon the frame 23 to cover the openings 22 and 24, as desired.

The fire box above the wall 6 and the pas sage 39 at the rear of thefire box and leading from the pocket 3G, communicate with a passage 40having a vertical branch 41 and a substantially horizontal continuation42. The branch passages 41 and 42 are formed by the provision of thevertical wall 43 and the horizontal base 44 vhich contain the oven 45.

The oven 45 is substantially rectangular in cross section with theexception that its base is of trough shape as at 46 and receives theburner pipe 47 extending from the front to the rear of the range andhaving small openings or air inlet ducts 48 in the rear andA front wallof the range, so that air may be admitted to support combustion. Therear wall 49 of lthe oven 45 is desirably spaced from the rear wall ofthe range and is provided with apertures 50 for the escape of theproducts of combustion when the gas burner 47 is being utilized. Vithinthe oven 45 and disposed in alinement upon the vertical walls thereoflare guides 51 for the reception of shelves or racks. The rack which Iprefer to use in this invention, is shown best in Figs. 8 and 9 andcomprises a body portion 52 and a spreader member 53, the said bodyportion having its forward end provided with downturned lips 54, theselips being formed upon the body portion so that the closing of the ovendoor 55 will serve to force the rack into proper position, if it beextended outwardly.

Mounted above the oven 45 and spaced therefrom is a partition 56 formingthe base wall of a broiler oven. In this space 1 desirably provide abatile plate 55, shown in Fig. 4 and extending from the rear wall ot'the range forwardly and at an angle, for a purpose to be hereinafterdescribed. This broiler oven has a false top 57 whereby there isprovided a horizontal chamber 58 having communication with the broilerby holes 59 in the false top 57. Inlet apertures 60 are provided in thefront of the broiler oven just below the name plate of the door 61, andburners 62 extend across the said broiler' oven, being fed by a gassupply pipe (i3, which forms a part of the gas supply pipe 28 hithertomentioned.

- The rear wall of the range is provided at a point near the upper lefthand corner of the oven 45, with an outlet aperture 64. Referring toFigs. 10, 11 and 12, it will be apparent that this aperture (i4 leadsinto a casting (35 which is mounted upon the outer surface of the rearwall of the range and together with such rear wall, forms a passage (36normally communicating with a passage G7 leading into a chimney pipe 68which extends upwardly in the rear of the range and which communicateswith the chamber 58 formed by the false top 57 above the broilerroven.such communication being effected through the medium of a casting (59,shown in Fig. 5. The communication effected with this chamber 58constitutes a draft checking apparatus, the operation of which will behereinafter described.

Mounted upon' the upper wall of the oven 45 near the upper lett-handcorner thereof is a hand operated damper of the structure .shown inFigs. 13 and 14 and provided at its rear end with a supplemental damper71 adapted to control the communication between the passages (56 and 67in the casting (35.

In operation as a coal stove, the burners 27 are removed and the pivotedcaps are swung into position to close the holes through which the pipesof said burners have passed, whereupon a re is built upon the rockinggrate bars 8. This fire may be either of wood or ot' coal. After thefire is built and lighted, a lid may be placed over the opening 22whereupon the products of combustion will take their natural course.lVhen the fire is rst lighted, the damper 70 is desirably lowered andpermits the -passage of the products of combustion up the verticalpassage 41 and over the top of the oven 45 directly into the passage 67forming the mouth of the chimney 68. It is advisable to leave thisinitial draft open until the fire has obtained a proper start. Thedamper is then closed, whereupon the products of combustion are sluitofi' from their directly upward ascent and thereupon take the path ot'least resistance, which is through the passage 42 beneath the oven andup upon the other side of the oven to the space above the oven, finallypassing to the passage 67. lt' it is desired to throw the heating effectupon the oven, the burners 35 in the pocket 3G may be lighted and theopening 24 covered. When this is done, the heat units pass into thepassage 39 in the rear of the fire bo'x and are delivered to the passage42, where they join with the products from the fire box, or it will beunderstood, that the fire box need not be utilized and with the burners35 lighted and the damper in closed position, the heat units will passthrough hunting means, :1nd 11 gaf: within Unch oi said Ovins.
